Will 73, 455, 4X heads bolt up to a 67 Bonneville 400 block? These heads would produce about 8:1 cr, I think. How about 75, 400, 6X heads? Thanks, Ed

use the compression calculator at the classicpontiac site for these questions. You can look up any details you need there for the input values for the calculations.

Unable to find a compression calculator at classicpontiac.com. Majority of threads is car dealers all offering the lowest priced Pontiacs.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
